We will have a brief downtime on Tuesday May 28 between 8:45 and 9:30 am PDT due to network equipment maintenance.

The Nitzschia putrida NIES-4239 genome sequence and gene models were not determined by the Joint Genome Institute (JGI), but were downloaded from Dryad on March 6, 2023. In order to ensure this genome is comparable to those sequenced by the JGI, we applied filters to remove if present: 1) transposable elements, 2) pseudogenes, 3) alternative transcripts and overlapping models, 4) alleles on secondary scaffolds and 5) unsupported short models. This resulted in the removal of 1,431 models and the generation of the FilteredModels1 (GeneCatalog) gene track. All published models are available in the ExternalModels track. Please note that this copy of the genome is not maintained by Kamikawa et al. and is therefore not automatically updated. In order to allow comparative analyses with other algal genomes sequenced by the JGI, a copy of this genome is incorporated into PhycoCosm. The JGI Annotation Pipeline was used to add functional annotation to this genome.

Nitzschia putrida strain:NIES-4239

Nitzschia putrida is an obligately heterotrophic species of diatoms, which lost its photosynthetic ability. In this project, whole-genome sequencing was conducted to gain insight into the evolutionary association between genomic evolution and lifestyle shifts from primary producers to consumers.
